SPECIFICATION forming part of Letters Patent No. 361,740, dated April 26, 1887.

Application filed February 1S, 1887. Serial No. 228,093. (No model.)

To all whom it may concern.-

Be it known that l, 'ALFRED O. YEATMAN, a citizen of the United States, residing at Wellington, iu the county of Sumner and State of Kansas, have invented certain new and useful Improvements in Car Couplers; and I -do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in car-couplers; and it consists in the construction and combination of parts, which will be fully hereinafter described, and pointed out in the claims.

The object of my invention is to p;ovide an improved automatic car-coupler, and Iobtain this object by the devices illustrated in the accompanying drawings, wherein the same letters of reference indicate the same or similar parts iu the two figures, and in which- Figure lis a longitudinal vertical section of my improved coupler, showing the pin in elevated position; and Fig. 2 is a similar view, showing the link coupled in the draw-head.

In the drawings, A represents a draw-head, which is cast in one-piece and provided with a rectangular recess, B, running longitudinally therethrough and communicating with a link-opening, B', in the front portion of said draw-head.

B2 is a vertical slot formed in the upper portion of the draw-head and adapted to receive and closely iit a coupling-pin, b, which also passes down through l[he front end of an elongated slot,O, formed in the bottom portion of said draw-head, and having its front wall in direct alignment with the front wall of the vertical slot B2, whereby said pin will protrude down through said slots and find a firm support along its front side when the link is coupled thereto.

The slot C is extended backward for some distance from the portion through which the pin b passes, and a pin, c, extends transversely across the same adjacent to its rear wall and is rigidly secured in the sides of the drawhead. This pin is constructed round or cylindrical in shape, for the purpose hereinafter described.

The forward upper half of the draw-head A,

at the front end of recess B, is extended downward for about half the diameter of the recess, as shown at a, thus leaving the front upper portion thereof closed, and causing the link when inserted to enter the lower portion of the recess B.

Situated within the recess B, and adapted to be slid backward and forward, is a bar, D,

constructed with a slightly-inclined lower side, 6o and with a lip, d, and an undercut portion, d', at itsfrontend. Averticalslot, e, is formed in the bar D, and extends forward beyond its center, and in this slot is pivoted, by a screwbolt, c, the upper end of a pendant, E, which vbar and through the pendant, and pass the screw-bolt c through the same, thereby secur- 7 5 ing them together. This screw-bolt forms a pivot, upon which the upperend of the pendant moves, is passed into place through an opening (not shown) in one side of the draw-head, and is removable by ordinary means. 8o Under the construction thus far described, with the bar D, provided with aslanting lower side, and with the vertical slot through the same arranged to extend forward beyond its center,with the weighted pendant attached by its upper end in said slot and in advance of the 'center of said bar, and with the fulcrumpin arranged in rear of the pendant, and against which the latter abuts when moved rearwardly with the sliding bar by the coup- 9o ling-link, it will be obvious that there will be a tendency for said pendant to move away from the fulcrum-pin and assume a vertical position, owing to the weight at its lower end seeking the center of gravity, and that in thus moving forwardly away from said pin it will slide the bar D forwardly inthe recess B,where Y it will normally remain, with its lug d beneath the lower end of the coupling-pin b, and hold the same from dropping down through loo the front part oi the bottom slot, C, until the coupling-link again moves the said bar rearwardly. /Vhen the link is inserted in the opening B in the draw-head, it is prevented from coming in contact with the lug d of the bar D by the downwardly-extending or closed portion a, above referred to, and is forced under said closed portion and against the lower undercut portion'of said bar, thereby permitward by the link the pendant,with the weight at its lower end, is forced into an inclined position, with its weighted end forward and its upper end backward, and a little to the rear of pin c, which acts as afulcrum, and permits the pendant to move easily or freely thereover. When the link is released by removing the pin the bar D, being then without obstruction at its front end, will be moved forward by the Weighted pendantleaving the inclined and assuming the vertical position.

My car-coupler, constructed and operating as described, is cheap, simple, strong, and not liable to get out of order, and hence will be found to possess great advantages over those heretofore employed.

Having thus described my invention, what I` `B, a downward extension, a, a coupling-pin slot, B, in its top portion, and an elongated slot, O, in its bottom portion, with a sliding bar, D, having a lug, d, and a cut-away p0rtion, d', at its front end, a rigid weighted pendant attached thereto, and a coupling-pin, b, adapted to rest upon the front end of said sliding bar, substantially as described.

In a car-coupler, the combination of a top and bottom slotted and longitudinally-recessed draw-head, A, provided with the downL ward extension a and the fulcrum-pin c, Vthe inclined bar D, having the lug d and recess d', the rigid Weighted pendant E, attached to said bar forward of its center, and a coupling-pin, b, resting upon the forward end of said bar, substantially as described.

3. In a car-coupler, the combination of a draw-head provided with coupling-pin slot in its top, an elongated bottom slot, a longitudinal recess having a partly-closed end, and a fulcrum-pin with aV sliding bar formed with an inclined lower side and with a lug and cutaway portion at its front end, a rigid weightedy ALFRED O.
